Description: Provides methods to perform block diagonal covariance
        matrix detection using singular vectors ('BD-SVD'), which can
        be extended to inherently sparse principal component analysis
        ('IS-PCA'). The methods are described in Bauer (2025)
        <doi:10.1080/10618600.2024.2422985> and Bauer (2026)
        <doi:10.48550/arXiv.2510.03729>.
